Yours obviously. Terrible design and awful colour choice. Not completely surprising from such a backwards country but I have to admit you raised the ugliness bar to a whole new level. Matches well with your ridiculous anthem and your stupid traditions (incest and cannibalism are still a thing I've heard).

My country on the other hand... now that's some nice flag design: good palette, great inspiration, high symbolic value. Very nice. Pairs well with our melodic anthem and our respectable traditions (like ritual 'feast of the elders' and ceremonial family acts of love)

Basically any flag that’s just 3 colored bars. They’re so boring and there are so many that it’s hard to even differentiate them.

Flags should say something about your country.

Australia & New Zealand. The two are too similar and IMO keeping the Union Jack on your flag while being an independent nation adds to the confusion. Canada had the right idea with the maple leaf.

All the tricolor ones. At least put something there ffs, Serbia and Slovakia did and it's still not great but much better.

Tie. Poland and Indonesia.

Any flag that cucks itself by having the union jack on it. Looking at you Oz/NZ... It's time to move on.

Bosnia and Herzegovina 🇧🇦 is so unbalanced it just feels wrong. At least you can't say it's boring.

I've always been annoyed at Ireland's because it replaced a much nicer flag.

Four bars is already too many, adding a big red line down the middle is not helping, and tbh if you took away the star it'd at least be symmetrical.

If your flag is gonna be busy, at least be creative and put like a dragon or something on it.

Sorry CAR.

Morocco has the worst colour scheme. Low contrast makes the star disappear when viewing from far away.

Lithuania maybe. Boring Tricolor and I don't like the color combination at all.

Bangladesh is so fucking asymmetric

WHY

The Torres Straight Islands flag is pretty bad. It looks like a cats arsehole.

Imo good contenders are Nicaragua and El Salvador for being so incredibly generic. At least other Central American countries have more unique designs.

Belgium.

Close tie between America and UK, both horrible color choices

Seychelles

Two random ones I find quite ugly are Madagascar and Samoa.

Brazil. Mostly because it has text. Actually, reading about the flag and its history has made me appreciate it more. FUCK! I'm changing my answer to Malaysia for copying my country's flag.
